i was wondering how i could make a ridge on the copper fuel pipe to stop the rubber pipe being blown off.
i got some olives and an 8mm male/female union,cut a slot in the female nut (took 1 side of the hex out) to slide over the side of the pipe,insert olive,tighten union,remove union,slide nut off of pipe and bingo
blue peter badge please

i tried that, and it didn;t tighten up correctly, it spread the nut.

i ended up using the fitting "as is", then cutting the nut off with a dremel afterwards.

another option is to get a steel ball bearing, and hit it into the end of the pipe to flare it.

Or you could get a solder ring fitting and put it on.

i just used the 1/4" flare on my brake line flaring tool kit. nice and easy

Solder the olive on.

Even cheaper, solder half the olive on!!!

anyway,i,m well pleased,all mounted up and throttle pedal actually does something now
